# How many questions and answers are asked in one day at Stack Overflow? [duplicate]

I was wondering how many question and answers are posted each day at Stack Overflow?

I have gone through how many questions are opened Daily on Stackoverflow?, but I didn't get a perfect answer.

For questions:

300 / hour

# 2.628M / year

Figure we do the math:

660 / hour

# Based on real data from the past year (Sept 2012 - Sept 2013):

There have been 2,170,441 Questions over the past year which calculates to about:

~247 / hour

# ~2.17M / year

There have been 3,275,577 Answers over the past year which calculates to about:

~374 / hour

# ~3.276M / year

• I updated my answer more @Bart MATH!! – Naftali aka Neal Oct 14 '13 at 13:53
• Pshh, math .... as if that has even proven anything. P.s. you might want to check your figures at the end there ... – Bart Oct 14 '13 at 13:54
• @Bart hmmm where did I go wrong? Did I do maths wrong?!?! – Naftali aka Neal Oct 14 '13 at 13:56
• 10.8k / 10 days --> ??? / 100 days – Bart Oct 14 '13 at 13:56
• 10.8K * 10 === 1.08 million... no? Unless I don't know my tens multiplication table.... CRAP!!! You are right!! – Naftali aka Neal Oct 14 '13 at 13:57
• @Bart silly me :-P the 1st number was wrong and the last one was right ^_^ I fixed it!! YAY~~~ ^_^ – Naftali aka Neal Oct 14 '13 at 13:59
• @amanaPlanaCAnalPAnaMA: That greats, i doesn't even guess these much answers are given.. – Toseef Khilji Oct 14 '13 at 14:00
• Don't tell me you came up with the correct last figure based on wrong assumptions about the previous ones. I should really have you look at my code. I never get stuff to work when it really shouldn't! – Bart Oct 14 '13 at 14:01
• @Bart lol I got the last figure first then did division. I put the decimals in the wrong places :-P – Naftali aka Neal Oct 14 '13 at 14:01
• What percentage of these questions remain on the site? I suppose most of them get closed and deleted. – Calmarius Oct 14 '13 at 14:05
• Is there a basis for "half of which have at least one answer..." and the following numbers or are they just an assumption? That would imply that the answer/question ratio is dropping, since overall the site has 11M / 5.9M answers to questions. – Geobits Oct 14 '13 at 14:07
• @Geobits I am making complete guesstimates. Given that there are 300 questions per hour. – Naftali aka Neal Oct 14 '13 at 14:08
• @Geobits updated with new numbers based on 77% answered as opposed to 50% – Naftali aka Neal Oct 14 '13 at 14:17
• So, TL;DR: A lot. – Rocket Hazmat Oct 14 '13 at 14:20
• @jmac Exactly and if you look at my calculations I factor that all in :-) – Naftali aka Neal Oct 14 '13 at 15:10

• @amanaPlanaCAnalPAnaMA `where PostTypeId = 2` so it means only answers, I'll fix the post. – Shadow 10 Years Wizard Oct 14 '13 at 14:48
